Forest fires cause unexpectedly large nutrient losses

Forest fires cause unexpectedly large nutrient losses. The carbon and nitrogen losses attributable to forest fires are much larger than was previously thought. This has now been shown by an extensive study that has compiled fire experiments from around the world.

Biologist receive 12 million crowns from EU

Christer Löfstedt and his colleagues have studied the butterflies' pheromones for almost 30 years. Now the results will be used in large scale production of insect pheromones. Photo: Christer Löfstedt A project that involves five European universities and four companies will mass-produce insect pheromones cheaply and biologically. The project aims at making these pheromones available on a large scale, and to replace poisonous insecticides in the fight against harmful bugs and other insects that threaten crops and forests.

Life under the surface in live broadcast

At Lund University in Sweden, researchers have invented new systems to study the life of microorganisms in the ground. Without any digging, the researchers are able to use microchips to see and analyse an invisible world that is filled with more species than any other ecosystem.

Scallop eyes can help develop smaller underwater cameras

Photo: Dan-Eric Nilsson, Lund University In an article in today’s issue of Science researchers from Lund and Israel present a detailed study of a scallop’s visual system. Their findings can help to develop devices for imaging applications.

Investment of several million SEK in sealed protein capsules

Ingemar André An extensive research project on the design of tiny protein containers has now been awarded a prestigious grant from the European Research Council, ERC. The grant of approximately SEK 20 million will go to researcher Ingemar André at the Department of Chemistry.

Researchers to create Virtual Reality model of the Milky Way

This could enable new types of discoveries that aren’t possible with current tools - perhaps even unraveling how the Milky Way was formed.

How horseflies find blood meals in dark environments

They received the award for showing that dark horses suffer more than white ones from horseflies. Now the scientists know how horseflies find dark-coated animals even in a dark environment.

Highly charged molecules behave paradoxically

Mikael Lund and Giulio Tesei. Chemistry researchers have now discovered how certain small biomolecules attach to one another. The researchers’ study also overturns the standard picture – particles with the same electrical charge appear to be drawn together and not vice versa. The results may be important for the development of new drugs.

Higher temperatures change the flora in Skåne

Wild radish (Raphanus raphanistrum) is one of the species in Skåne that is much harder to find now than in the 1900s. Photo: Torbjörn Tyler A survey of the wild flora in Sweden’s southernmost county, Skåne, reveals that far more species have decreased in number than species that show an increase. Most species that are easier to find now than a few decades ago are invasive and have been spread by humans. A warmer climate and changes in agriculture have caused the changes in the flora.

Species in the north are more vulnerable to climate change

The researchers have studied two species of damselflies. Photo: Viktor Nilsson-Örtman For the first time, researchers have proposed the hypothesis that animals that live in climate zones at a safe distance from both the poles as well as the tropics have the most to gain from acclimating to changes in climate. The findings contradict previous research in the field.
